SPECIFICATION forming part of Letters Patent No. 760,558, dated May 24, 1.904;

Application led April 28, 1903.

T0 (if/ZZ whom, t nca/y concern.'

Be it known that we, HERMAN H. PATRY and LoUIs SAMUEL HANsoN, citizens of the United States, residing at Cloquet, in the county of Carlton and State of Minnesota, have invented certain new and useful Improvements in Watchcase Construction, of which the following is a specification.

This invention provides a watchcase of the hunting type capable of being manufactured at a reduced cost and involving a less number of parts, the inside back cover and two hinges being dispensed with, and which will be dustprooi' and have the case-lift and catch-springs located exterior to the band and in the space formed between it and the case.

For a full description of the invention and the merits thereoil and also to acquire a knowledge of the details of construction of the means for effecting the result reference is to be had to the following description and drawings hereto attached.

While the essential and characteristic features of the invention are susceptible oi' modiiication, still the preferred embodiment of the invention is illustrated in the accompanying drawings, in which- Figure 1 is a front View oi' a watch embodying the invention, the front cover being open. Fig. 2 is a side view, the front cover being open and the back and bezel detached. Fig. 3 is a central transverse section of the case on a larger scale, the movement and front cover being omitted. Fig. 4 is a perspective view of the band. Fig. 5 is'a central transverse section of the band. Fig. 6 is asection of the case about on the line X X of Fig. 3 looking' to the left, showing the position of the lift and catch springs. Fig. 7 is a perspective view of the catch-spring. Fig. 8 is a perspective view of the lift-spring. Fig. 9 is side view oil the band and bezel, showing a slip-joint formed between them, the bezel being detached and an edge portion broken away and showing the parts of the joint similarly inclined.

Corresponding and like parts are referred 'to in the following description and indicated 'in all the views oi' the drawings by the same reference characters.

serial N5. 154,710. (No model.)

The case-center is indicated at 1 and com'-l prises inner rims 2 and 3, the latter being' wider than the former in order to engage with the shoulder 4 of band 5 and support same from displacement in one direction. The pendant 6 oi' the stem projects from the case 1 and is internally threaded to receive nut 7, connected to stem 8 by abushing-joint. Packing 9 is slipped upon the upper end of stem 8 and is confined between nut 7 and bushing 10 and is clamped by crown 11, secured to the upper end of stem 8. Packing 9 insures the formation of a dust-prooi lioint between stem 8 and adjunetive parts. Band 5 is of a size to snugly lit within case l and is provided with outer shoulder LLfor engagement with inner rim 3 and with inner shoulder 12 for engagement with the movement (not shown) to support same in the accustomed way. The band is provided with threaded extensions 13 `and 14, the latter projecting beyond inner rim 8 of case l to receive cap or back cover 15 and threaded extension 13, adapted to receive bezel 16, the case being coniined between bezel 16 and cap 15, the iit between the parts being such as to exclude dust and moisture. Band 5 is provided with an opening to admit oi' the passage of stem 8 and is likewise notched for the passage of lever 17 of the type of movement adapted to have its hands-setting mechanism thrown into gear by means of a lever or lateral sliding extension.

The front cover 18 is hinged to case 1 in the usual way and when released from the catchspring is thrown open by lift-spring 19, same being located in the space formed between band 5 and case 1. Catch-spring 20 is similarly located in the space formed between band 5 and case 1, and its active portion is adapted to engage with cover 18 and hold same closed against the action of lift-spring 19 in the manner well understood. It is noticed that both springs 19 and 2O are located exterior to band 5, thereby preventing the formation of any openings in band 5 which would admit dust or moisture.

The cap or back cover 15 protects the movement in the rear, and the cover 18 performs the same oitice for the front. All the advantages oi' the usual hunting-case are attained IOO without the expense attendant upon the provision of the inside back cover, which in the present instance is dispensed with. By having the cap or back cover 15 and bezel 16 connected to band 5 by a screw-thread joint a tight joint is insured, and the parts may be readily disconnected by the proper application of force to loosen and admit of unscrewing the parts. The lirst cost is reduced as to material and labor, and the timepiece is materially lightened and enabled to be of smaller size with a movement of given diameter and thickness.

The construction of case illustrated is principally designed for stem-setting movements; but when the invention is applied to lever-set movements the bezel and band are notched to admit of the lever working between them, as illustrated most clearly in F ig. 9. The crown 11 overlaps shell 6 a sufficient distance to prevent exposingthe joint when stem 8 is moved outward to throw the hands-setting mechanism into gear. The'case is prevented from movement in one direction with reference to the band by the back 15 and from movement in the opposite direction by bezel 13, said parts 13 and l5 clamping opposite sides of the ease and acting jointly therewith and with the band to hold the movement against displacement. To insure correct positioning' of band 5 and prevent turning thereof in the case when screwing or unscrewing the back and bezel, pin 23 extends outward from the band and is adapted to enter a notch or depression 24 of the case.

Having thus described the invention, what is claimed as new isl. In watchcase construction, the combination of the ease-center having spaced rims extended inward to unequal distances to form openings of varying diameter at opposite sides, a band insertible through the larger opening at one side oi the case and having' an outer shoulder to engage with the inner side of the rim at the opposite side of the case, and having a reduced end portion passed through and beyond said rim, and a clamp-piece threaded upon the projected end of the band to coniine the inner edge portion of the rim between said shoulder and clamp-piece, substantially as set forth.

2. In watchcase construction, the combination of the case-center having spaced rims extended inward to unequal distances to vform openings of varying diameter at opposite sides, a band insertible through the larger opening at one side of the case and having' an outer shoulder to engag'e with the inner side of the rim at the opposite side of the case, and havinga reduced end portion passed through and beyond said rim and having' its opposite end portion exteriorly threaded and extended beyond the side of the ease-center having the larger opening, a bezel threaded upon one end of the band and a cap threaded upon the opposite end to clamp the case-center between them, one of said parts also serving to clamp the wider rim of the case-center against the shoulder of the band,substantiall y as set forth.

ln testimony whereotl we ailix our signatures in presence of two witnesses.
